At the age of three Urs started playing little melodies on the piano. Later he developed a great passion for playing drums. With his teacher Pierre Favre he began to target a career as a jazz drummer. At the young age of 12 he was already touring with the Big Band of Fernsehen DRS, the national TV station, and was soon regarded as one of the greatest young talents of the Swiss music scene. What followed were several years of gigs in the best reputated jazz clubs in Switzerland where he played with his older brother, the jazz pianist Chris Wiesendanger.

When Urs turned 15 he began to write his first pop songs and also started producing. He definitely gave his career a new direction. Only a short while later he began producing full time. Since then Urs has worked with a lot of the best known Swiss artists like DJ Bobo, Nubya and the Swiss Pop Idol show winner Carmen Fenk. He produced half of the album of Carmen Fenk in early 2004 and wrote one song for her.

Urs, without exaggeration, can be titled as one of the most skillful arrangers in Europe. Even more. He has not to shy away from a comparison with the cats in the US. He's worked many times in Los Angeles with some of the greatest musicians there. For example, he did arranging jobs on the albums "Midnight" and "State of Grace" by Jeff Lorber. Furthermore, he's worked with sax players Dave Koz and Warren Hill, producer Mickey Petralia, drummer John Robinson, guitarists Chris Camozzi, Michael Landau and Dean Parks, vocalist Warren Wiebe and and countless others.
